SPECIFICATION forming part of Letters Patent 1\T o. 688,591, dated December 10, 1.901.

Application inea my 9,1960.

To @ZZ whom, t may concern,.-

Beit known that I, GEORGE W. CARY, a citizen of the United States, residing at New Bedford, in the 'county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Motor-Vehicles, of which the following is a specification.

This invention has reference to an improvement in motor-carriages and other moio tor-propelled vehicles; and it consists in the peculiar and novel construction andthe combination of parts whereby a plurality of motors is supported in the hub of the wheel and supplied with active force through tle axle I5 on which the wheel revolves, as will be more fully set forth hereinafter.

In motor-vehicles propelled by the force of steam, gas, or explosive mixtures the engine or motor is usually supported on part of the 2o carriage and connected with one of the axles so as to rotate the wheels connected with the axle, and thereby propel the vehicle. The vibration of the motor and the axle affects the connecting mechanism injuriously. It

has also been suggested to mount the motor in one of the wheels and connect the same by means of a crank to the axle.

The object of this invention is to exert a more positive power on the Wheel by a plu- 3o rality of motors carried by the wheel and to inclose the motors in an impervious case forming the hub of the Wheel.

Figure lis a side view of a wheel, indicating in broken lines a plurality of motors connected with a central gear. Fig. 2 is a side View of the case forming the hub of the wheel, showing threel motors connected to gears which engage with a central gear and cams for controlling the operation of the motors.

4o Fig. 3 is a transverse sectional view of the hub on the line X X o f Fig. 2 extending through the axle, showing the connection of the motors to the central gear secured to the axle. Fig. 4 is a sectional view, on an enlarged scale, of one of the motors. Fig. 5 is a side view of one of the arms connecting the valve-stem of one of the motors with the controlling-cam. Fig. 6 is a diagrammatic View Serial No. '23,001. (No model.)

showing the motor-controlling cam and operation of the same.

The drawings show the construction and arrangement of the parts as constructed to use steam as the motive force.

Similar marks of reference indicate corresponding parts in all the figures.

In the drawings, A indicates the wheel of a vehicle, which may be of any suitable construction. In the preferred form the construction employed in a bicycle-wheel is used. The cylindrical case @,having circular sides, forms the hub of the wheel. The annular flanges a/ are perforated to receive the stay-rods of the wheel. The case a is made oil-tight, so thatlubricating-oil may be carried in the casey to lubricate the moving parts. The two sides of the case a are provided with the rollerbearings a2 a2, the cones a3 a3 of which are adjustably secured to the axle b. This axle is provided with the longitudinal duct b, through which steam is conducted to the motors contained in the case a, and with the duct b2, by which the exhaust from the motor is discharged.

The gear b3 is rigidly secured to the axle b. The annular chamber b4 is rotatably supported on the axle between rings secured to the axle. Radially-disposed openings in the wall of the axle connect the inlet-ductb' with the annular chamber b4. On the opposite side of the gear b3 another annular chamber b5 is rotatably supported on the axle between rings secured to the axle and connects by an opening in the same with the exh aust-ductl.

The cylinders 296, provided with the valvechambers 67, are secured to the hub-casing a and rotate with the same around the axle The piston bs of each of the cylinders b is connected by the connecting-rod b9 with the wrist-pin blo, which projects from the gear b, journaled on the post Z912, which is secured to one of the circular plates of the hub-casing a. The cam-plate 513 is'also journaled on the post Z912 and is secured to the hub of the gear bu, so as to rotate with the same. The arm 514 is formed, as shown in Fig. 5, so as to avoid contact with the gear b and the fixed central gear 53. On one end of the arm 514 the roller 515 is -journaled on a stud secured to the arm. 'The other end of the arm 514is secured to the valve-rod 51, which, extending through a stufiing-box, connects with the valves 517 and 518 in the valve-chamber 57.

The steam-supply pipe 519 connects the annular chamber 54 with the side inlet to the valve-chamber, and the exhaust-pipe 520 connects the upper part of the valve-chamber with the annular chamber 55.

The motors are single-acting steam-motors, three of which are preferably used. As shown in Fig. 4, the parts are all in the positions they occupy when the piston has reached the outward stroke and the exhaust of the waste steam is completed. The valve is moved to supply the steam for the next stroke as is shown in Fig. 6.

The three gears 511511 engage with and travel around the geark53 as they would on a xed circular rack and carry the hub-casing, on which their journals are secured, with them, thereby rotating the wheel. One or more wheels of a vehicle may be provided with the motors.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a vehicle-wheel, in combination with the hub of the wheel, of a multiple of motors secured to and turning with the wheel, gears connected with and turned by each of lthe motors and journaled on posts secured to the hub of the wheel, and a fixed central gear supported on a fixed part of the motor, the gears connected with the motors rolling on the central gear, as described.

2. In a vehicle-wheel, the combination with `the Wheel, of a central gear, and a multiple of motors each connected with a gear journaled on a post and engaging with the central gear, as described.

3. In a vehicle-Wheel, the combination with the axle, ducts in the axle, and a gear secured to the axle, of an annularsteam-supply chamber, au annular steam-exhaust chamber, a multiple of steamm otors secured to the wheel, gears in mesh with the central wheel and jour- 5o naled on posts secured to the wheel, connections between the pistons of the motors and the gears, and steam-supply and steam-ex haust connections between the annular steam supply and exhaust chambers, as described.

4. In a motor-vehicle, the combination with the wheel, of a hub consisting of a cylindrical casing, a fixed axle, ducts in the axle, rollerbearings for the casing on the shaft, and a gear on the axle, of a multiple of motors contained in and secured to the hub, gears engaging with the gear on the axle and journaled on posts secured to the casing, connections betweenthe gears and the motors, and connections between the motors and the ducts in the axle, as described.

5. A motor for vehicles having a plurality of cylinders, valve-chambers connected with the cylinders, a central gear, gears engaging with the central gear, connections between the gears and the pistons of .the cylinders, cam-plates secured to and rotating with the gears, valves in the Valve-chambers, connec-v tions between the cam-plates and the valvestems of each motor, and steam-supply connections and steam-exhaust connections with the valve-chambers, as described.

6. In a motor of the nature described, the combination with a central gear, of the cylinder 56, the valve-chambers 51, the pistons 5B in the cylinders, the gears 511 engaging with the central gear, the connecting-rods 59 connectinegthe pistons 58 with the wrist-pins on the gear 511, the cam-plates 51a secured to and turning with the gears 511, the piston-rods516 provided with the Avalves 517 and 518, the arm 514 connecting the cam-plate with the piston-v rod to operate the valves, connections be tween the steam-supply and the valve-charnbe-rs, and connections between the valvechambers and the exhaust-duct, whereby the steam supply and the exhaust are auto matically controlled to operate the motors successively, as described.

In testimony whereof I have signed my name to this specification in the presence ot' two subscribing witnesses.

GEORGE W. CA RY.
